I have a nice R-4C that has an issue I have never seen before. The AGC only 
functions in Slow mode. The AGC switch checks out as  does the Function switch. 
A previous owner had jumbled the wires to the AGC switch (probably trying to 
fix the problem)- I am close to 100% sure they are now correct- but the problem 
 persists. In all positions except Slow, the AGC voltage is high, around -75VDC 
 from memory and thus cuts off the stages controlled  by AGC. In Slow, the RX 
appears to function normally and S meter readings  are OK.

Anyone have a suggestion?
